Hello everyone,
can you help me with the following problem.

In fact, a certain event occurs again and again. When the Events occurs, 
I want to record the data shortly before the event until shortly after 
the event. These should be saved on the measuring device so that I can 
analyze them at a later time. The measuring device sould work autonomous 
without a connected PC and should be as small as possible .
Does anyone have experience with measuring devices that meet these 
requirements or can someone recommend certain devices?

Thank you and best regards
Elias

Some nanoseconds or a few days?

In fact: you didn't post any concrete requirements.

Check with your calendar if this probably Christmas, New Year's Eve or 
your birthday.
